Note: Population aged 12 and over who reported having 5 or more drinks on one occasion, at least once a month in the past 12 months. A definition change was implemented in 2013 to conform with the World Health Organization (WHO) and Health Canada guidelines for heavy drinking. Heavy drinking refers to males who reported having 5 or more drinks, or women who reported having 4 or more drinks, on one occasion, at least once a month in the past year. While this indicator remains comparable for males to the 5 or more drinks indicator published in previous years, it is no longer comparable for females.Source: Statistics Canada, CANSIM, table 105-0501 and Catalogue no. 82-221-X.
